Answer:
(- 4, - 7)
Step-by-step explanation:
given the 2 equations
2x - 3y = 13 → (1)
4x - y = - 9 → (2)
multiply all terms in (2) by - 3
- 12x + 3y = 27 → (3)
Add (1) and (3) term by term
(2x - 12x) + (- 3y + 3y) = (13 + 27)
- 10x = 40 ( divide both sides by - 10 )
x = - 4
Substitute x = - 4 in either (1) or (2) for corresponding value of y
(1) : - 8 - 3y = 13 ( add 8 to both sides )
- 3y = 21 ( divide both sides by - 3 )
y = - 7
Solution is (- 4, - 7 )
Answer:
we not form 60 3
Step-by-step explanation:
Answer:
the slope is 2 and the y intercept is 1.
Step-by-step explanation:
find 2 points and plug into this formula. (Y2-Y1)/(X2-X1)
(3-1)/(1-0)=2
y intercept is just when X equal to 0, what is y. Therefore, find X=0 on the graph. X=0, Y=1
Answer:
Janet makes 9 dollars per hour which is more that Giovanna makes.

The probability that none of them are spades is c(39,5) / c(48,5).
Probability is without a doubt how probable something is to show up. whenever we are uncertain about the final results of an occasion, we can talk about the possibilities of sure outcomes and how probable they are. The analysis of events governed by opportunity is referred to as records.

Coverage companies use possibility statistics to determine the possibility of having to pay out a declaration. A simple chance is calculated by way of dividing a particular outcome by all of the feasible outcomes.
